Figure 1. Functional profile of the metagenomes based on KEGG identifiers.

Figure 1

(a) PCA of the seven metagenomes using the lower hierarchical functional level; (b) Relative abundance (%) of microbial functions and pairwise comparison between RWS (1W, 3W and 10W) and TWS (1T, 3T and 10T) samples, red dots represent functions within the ABC transporters; (c) Highly enriched specific functions (compared with soil inoculum FS1) along three sequential transfers (fold-increase). Abbreviations: ABC transporters (ABCT), two-component system proteins (TCSP) and phosphotransferase systems (PTS).
